This paper, grounded in mobility theory, examines the ideological evolution of Guo Moruo across three distinct life stages: youth in Sichuan, revolutionary period in Shanghai, and exile in Japan, with a particular focus on spatial trajectories. Drawing on Tim Cresswell’s threefold dialectical framework of mobility, the study analyzes how Guo Moruo’s geographic movements influenced his literary production, ideological transformation, and identity formation. The paper seeks to move beyond the conventional approach centered on “ideological content analysis,” and instead reinterprets Guo Moruo’s intellectual development through the lens of spatial-ideological interaction. In doing so, it offers a new theoretical perspective and methodological approach for understanding the ideological shifts of modern Chinese intellectuals.
